Alex Aiono got the black and yellow dress code memo as he stepped out for The LEGO Batman Movie yesterday in Los Angeles.

The musician has a song on the official soundtrack for the movie and Alex was so excited to tell his fans.

“Lego Batman soundtrack FEATURING MY VERSION OF MAN IN THE MIRROR is out tomorrow!!! The movie comes out February 10th!!!!! Check out this snippet!!” he wrote earlier in the week on Instagram.

Alex added later after the premiere, “What an incredible day. Today I heard my voice singing in a Major Motion Picture, The Lego Batman Movie. Thank you to everyone who made this opportunity possible.”
